The diagram below represents cons nearby galaxies, called the Hubble sequence: 3% are elliptical, lenticular 15%, 72% spirals, 10% irregular. Image: Image formed by the photographs of galaxies made with Hubble Space Telescope and the Sloan Digital Sky Survey. They were placed in order of classification of the Hubble sequence (E: elliptical galaxies, S0: Lenticular galaxies; Sa_b_c_d: spiral galaxies, Pec: irregular galaxies). The diagram shows the nearby galaxies, called the Hubble sequence: 3% are elliptical, lenticular 15%, 72% spirals, 10% irregular. | |
